In an attempt to further improve my system performance, I embarked on the task of doing a Registry Defrag. This was suggested in a few different postings I'd read about Windows Vista optimization.
I downloaded three programs to try out: Free Registry Defrag, WinASO Registry Optimizer, and Auslogics Registry Defrag.
I tried each one after shutting down all applications (including the widget sidebar). In all cases, as the analysis process proceeds I don't touch anything else on the computer. About 10 to 15 minutes into the process, I begin to wonder what's taking so long. In two of them, a progress bar gets to 99% and just sits there. Another shows 3 out of 13 tasks and also can't seem to go beyond this.
At about this point, my user interface freezes in various stages. I can move my mouse, but I can't launch anything new from the Start Menu, or click on a desktop icon. Then, my cursor becomes unresponsive to my external mouse or touchpad. I also start to notice that the clock in the lower right corner is no longer updating. Other times I walked away for about 20 minutes and came back to see that my screen went to sleep (but all lights show active). Touching the mouse should "wake up" the screen, but nothing happens. The user interface is unresponsive.
Why... why do 3 different applications freeze up on me like this? Is Registry Defragging fraught with problems? Or, is it possible that some background process is interfering with it, something that the programs don't bother to detect before proceeding? Any ideas?
